With reference to Hemoglobin, consider the following statements:1. It ...
Hemoglobin is the iron-containing oxygen-transport metalloprotein in the red blood cells of all vertebrates (with the exception of the fish family Channichthyidae) as well as the tissues of some invertebrates.

Carbon dioxide is transported in the blood from the tissue to the lungs in three ways: o dissolved in the blood or buffered with water as a carbonic acid or bound to proteins, particularly hemoglobin.
Each hemoglobin protein is made up of subunits called hemes, which are what gives blood its red color. More specifically, the hemes can bind iron molecules, and these iron molecules bind oxygen. The blood cells are red because of the interaction between iron and oxygen. Hemoglobin in the blood carries oxygen from the respiratory organs (lungs or gills) to the rest of the body (i.e. the tissues). There it releases the oxygen to permit aerobic respiration to provide energy to power the functions of the organism in the process called metabolism.
Hence all the options are correct.

With reference to Hemoglobin, consider the following statements:1. It ...
Explanation:
Hemoglobin is a protein molecule found in red blood cells (RBCs) that plays a crucial role in the transportation of oxygen and carbon dioxide in the body. It is responsible for the red color of blood.
The main functions of hemoglobin include:
1. Imparts red color to blood
Hemoglobin contains iron, which binds to oxygen and gives blood its characteristic red color. When oxygenated, hemoglobin turns bright red, and when deoxygenated, it turns dark red.
2. Carries oxygen in the blood
One of the primary functions of hemoglobin is to transport oxygen from the lungs to the body tissues. In the lungs, hemoglobin binds to oxygen molecules, forming oxyhemoglobin. This oxygenated hemoglobin then travels through the bloodstream, delivering oxygen to cells and tissues that require it for various metabolic processes.
3. Transports carbon dioxide from tissues to lungs
Hemoglobin also plays a vital role in carrying carbon dioxide, a waste product of cellular respiration, from the body tissues to the lungs for exhalation. As cells produce carbon dioxide, it diffuses into the bloodstream and binds to hemoglobin, forming carbaminohemoglobin. Hemoglobin then transports this carbon dioxide back to the lungs, where it is released and exhaled.
In summary, hemoglobin performs all three functions mentioned in the given statements. It imparts the red color to blood, carries oxygen from the lungs to body tissues, and transports carbon dioxide from the tissues back to the lungs. These functions are essential for maintaining the proper oxygenation and removal of waste products in the body.
